TECHNICAL FIELD

This patent document pertains generally, but not by way of limitation,to an orthopedic device, tool, or instrument holder including auniversal connection.

BACKGROUND

Tools or other instruments can be used by a surgeon to complete asurgical procedure (e.g., an orthopedic procedure). For example,intramedullary rods, drill guides, reamers, and pin and screw driverscan be used during the orthopedic procedure. During the procedure, whendifferent instruments or devices are being used, the surgeon may have toswitch between various device holders, which can increase surgery time.

OVERVIEW

The present inventors recognize, among other things, that a two-wayquick connection and release configuration for a tool or device can bebeneficial. The two-way connection allows the orthopedic device holderto be used in different configurations depending on the type oforthopedic tool being used and the preference of a surgeon.Additionally, a single activation can quickly connect and release theorthopedic tool at each configuration. The orthopedic device holder canbe readily used with different orthopedic tools of differing sizes.

DETAILED DESCRIPTION

The present orthopedic device holder (hereinafter referred tointerchangeably as “device holder”) is configured to provide a quick andeasy releasable connection for a plurality of orthopedic devices. Thedevice holder can include a two-way connection such that the operatorcan select which connection configuration to use. The orthopedic deviceholder can also prove useful in applications to provide a securable,releasable connection for a plurality of different orthopedic devicesused during an orthopedic procedure. The orthopedic device holder andits components can be made of a wide variety of materials, such as metalalloys, stainless steels, aluminum, titanium, polymers, or carbon fiber.

FIG. 1 illustrates an exploded view of an orthopedic device holder 2.The device holder 2 can include a body portion 4, a plunger portion 14,a locking sleeve 16, a locking bar 18, a resilient member 20, and alocking lever 22. The body portion 4 can include a proximal end 8 and adistal end 6. The body portion 4 can define a first bore 10 extending ina direction that is substantially perpendicular to a longitudinal axis46 of the body portion 4. In an example, the first bore 10 can extend ina direction that forms an oblique angle relative to the longitudinalaxis 46 of the body portion 4. In an example, the first bore 10 canextend from a first surface 11 of the body portion 4 to a second surface12 of the body portion 4. In another example, the first bore 10 canextend through a portion of the body portion 4.

The plunger portion 14 can include a proximal end 24 and a distal end26. As discussed herein, the plunger portion 14 can extend into achannel 36 of the body portion 4. The plunger portion 14 can define asecond bore 28 of the body portion 4. As discussed herein, the firstbore 10 and the second bore 28 have substantially identicalcross-section geometries such that an orthopedic device can beinterchangeably coupled to either the first bore 10 or the second bore28.

The locking sleeve 16 can be slidably mounted on the plunger portion 14and can be moveable between a first position and a second position. Whenthe locking sleeve 16 is in the first position, the locking sleeve 16can be in a locked configuration with respect to the second bore 28.When the locking sleeve 16 is in the second position, the locking sleeve16 can be in an unlocked configuration with respect to the second bore28.

The locking bar 18 can include a proximal end 32 and a distal end 30. Inan example, the locking bar 18 can be operably coupled to the bodyportion 4. The locking bar 18 can be moveable between a first positionand a second position. When the locking bar 18 is in the first position,the locking bar 18 can be in a locked configuration with respect to thefirst bore 10. When the locking bar 18 is in the second position, thelocking bar 18 can be in an unlocked configuration with respect to thefirst bore 10.

The locking lever 22 can be operably coupled to the body portion 4. Thelocking lever 22 can operate as the single activation mechanism thatconnects and releases an orthopedic tool at each connection point (e.g.,the first bore 10 and the second bore 28) of the device holder 2. Thelocking lever 22 can be configured to move between a first position anda second position. When the locking lever 22 moves from the firstposition to the second position (e.g., by a user pressing on the lockinglever 22), the locking lever 22 can simultaneously transition thelocking bar 18 and the locking sleeve 16 from the respective firstpositions to the respective second positions. Thus, a single activationcan transition the orthopedic device holder 2 from a lockedconfiguration to an unlocked configuration at each connection point.

The resilient member 20 can include a proximal end 19 and a distal end21. The resilient member 20 can be positioned around the proximal end 24of the plunger portion 14. Additionally, the resilient member 20 can bepositioned between the locking sleeve 16 and an interior ledge 38 (asshown in FIG. 2B) of the body portion 4. When the locking lever 22 is inthe first position, the resilient member 20 can be in an expanded state.Additionally, when the locking lever 22 is in the second position, theresilient member 20 can be in a compressed state such that when, forexample, a user releases the locking lever 22, the locking lever 22 willtransition from the second position to the first position due to theforce stored in the compressed resilient member 20. As the locking lever22 transitions from the second position to the first position, thelocking sleeve 16 and the locking bar 18 can also transition from therespective second positions to the respective first positions.

FIG. 2A illustrates a rear view of a body portion 4, as constructed inaccordance with at least one example. As illustrated in the example ofFIG. 2A, the first bore 10 has a tri-lobe cross-sectional shape. Thatis, the first bore 10 includes three substantially flat surfaces 34A-34C(collectively referred to as “substantially flat surfaces 34”). In anexample, the substantially flat surfaces 34 can be positionedequidistant from each other. In an example, the body portion 4 caninclude a counter-bore 35 having a diameter larger than the diameter ofthe first bore 10.

FIG. 2B illustrates a side view of the body portion 4 in FIG. 2A. Asillustrated in FIG. 2B, the first bore 10 can extend from the firstsurface 11 to the second surface 12. In an example, the first bore 10can be substantially perpendicular to a longitudinal axis 46 of the bodyportion 4. In another example, the first bore 10 can form an obliqueangle relative to the longitudinal axis 46. The body portion 4 candefine a channel 36 that can receive the proximal end 24 of the plungerportion 14 (as shown in FIG. 1). The body portion 4 can define a space44 that can receive, when assembled, at least a portion of the plungerportion 14, the locking sleeve 16, the locking bar 18, and the resilientmember 20 (as shown in FIG. 8). The space 44 can define a ledge 38 thatcan engage with the resilient member 20 (as shown in FIG. 8).

The body portion 4 can include at least one opening 40 in a side wall ofthe first bore 10. The at least one opening 40 can be configured suchthat it extends into an interior 48 of the first bore 10. In an example,the body portion 4 can include two openings 40 extending into theinterior 48 of the first bore 10. In still another example, the bodyportion 4 can include more than two openings 40 extending into theinterior 48 of the first bore 10. The body portion 4 can also define anindentation 50. As described herein, the indentation 50 can interactwith the locking bar 18 as the locking lever 22 is transitioned from thefirst position to the second position. The body portion 4 can alsodefine a locking hole 42 that can receive a locking bar 106 to lock thelocking lever 22 to the body portion 4 (as shown in FIG. 8).

FIG. 3A illustrates a perspective view of the plunger portion 14, asconstructed in accordance with at least one example. FIG. 3B illustratesa side view of the plunger portion 14 in FIG. 3A. The distal end 26 ofthe plunger portion 14 can include a head portion 52 that is configuredto couple with the channel 36 (as shown in FIG. 2B) in the body portion4. For example, the head portion 52 can define a protuberance 62 thatcan engage with a protuberance within the channel 36 of the body portion4. The plunger portion 14 can also include an elongate body portion 60that can define the second bore 28. The plunger portion 14 can alsoinclude at least one opening 56 extending into an interior 72 (shown inFIG. 3C) of the second bore 28. For example, the opening 56 can extendfrom an exterior surface 70 of the plunger portion 14 to the interiorsurface 72 (shown in FIG. 3C). In an example, the plunger portion 14 caninclude two openings 56. In another example, the plunger portion 14 caninclude more than two openings 56. As illustrated in FIG. 3A, theelongate body portion 60 can further define a longitudinally extendingslot 58. In an example, the elongate body portion 60 can include twolongitudinally extending slots 58 that are diametrically opposed fromone another. As described herein, the longitudinally extending slot 58can receive a portion of the locking bar 18 such that the locking bar 18can move in a direction along the longitudinally extending slot 58.

FIG. 3C illustrates a cross-section of the plunger portion 14 in FIG. 3Balong lines 3C-3C. As illustrated in FIG. 3C, the plunger portion 14 candefine two openings 56 that extend from the exterior surface 70 to theinterior surface 72. The second bore 28 can have a diameter 64 fromabout 7.0 millimeters to about 7.5 millimeters. In some examples, thehead portion 52 can define an opening 71 that includes include one ormore diameters (e.g., diameter 66 and diameter 68). In an example,diameters 66, 68 can be different from the diameter 64 of the secondbore 28. In an example, diameters 64, 66, and 68 are different from eachother. In another example, the diameters 66, 68 can be equal to eachother but different from diameter 64. In still another example,diameters 64, 66, and 68 can be substantially equal.

FIG. 3D illustrates a cross-section view of the plunger portion 14 inFIG. 3B along lines 3D-3D. As illustrated in FIG. 3D, the second bore 28includes three substantially flat surfaces 76A-C (collectively referredto as “substantially flat surfaces 76”). The substantially flat surfaces76 can be positioned equidistant from each other. In an example, betweenadjacent substantially flat surfaces 76A-C can be a curved surface. Forexample, the curved surface can be a concave surface. In an example, alength of each one of the substantially flat surfaces 76 can besubstantially equal. In an example, an angle 80 formed by lines 82, 84that are tangent to two adjacent substantially flat surfaces 76 (e.g.,flat surface 76B and flat surface 76C) can be about 60 degrees. In anexample, a diameter 78 extending from a substantially flat surfaces(e.g., substantially flat surface 76B) to a midpoint of a curved surface(e.g., surface between substantially flat surface 76C and 76A) can befrom about 7.0 millimeters to about 7.5 millimeters. In an example, oneof the substantially flat surfaces 76 can be aligned with one of theopenings 56 of the plunger portion 14. For example, substantially flatsurface 76A can be aligned with one of the openings 56.

As illustrated in FIG. 3D, locking balls 74 can be shaped and sized suchthat a portion of the locking ball 74 can extend into the second bore 28when the locking lever 22 (as shown in FIG. 1) is in the first position.The substantially flat surfaces 76 can be configured to engage withcorresponding substantially flat surfaces of an orthopedic device thatis positioned within the second bore 28. The engagement of thesubstantially flat surfaces 76 of the second bore 28 and thesubstantially flat surfaces of the orthopedic device can allow forrotational constraint. That is, as rotational motion is applied to thebody portion 4, the body portion 4, as well as an orthopedic devicepositioned within the second bore 28, will rotate together. As discussedherein, the locking balls 74 can be configured to extend through the atleast one opening 56 in the plunger portion 14 and fit into a matingrecess of an orthopedic device. The engagement of the locking balls 74and the mating recess allow for axial constraint of the orthopedicdevice. That is, as force is applied along the longitudinal axis (e.g.,pushing or pulling), the orthopedic device can move simultaneously withthe orthopedic device holder 2. Thus, the orthopedic device holder 2 canallow for rotational and axial constraint of an orthopedic devicepositioned within the second bore 28. While FIG. 3D is discussed withreference to the second bore 28, the first bore 10 can have the samedimensions such that an orthopedic device can be coupled to either thefirst bore 10 or the second bore 28.

FIG. 4A illustrates a side view of a locking sleeve 16, as constructedin accordance with at least one example. FIG. 4B illustrates a frontview of the locking sleeve 16 in FIG. 4A. The locking sleeve 16 can bepart of a locking mechanism that can be configured to couple anorthopedic instrument within the second bore 28 (as shown in FIG.3A-3C). The locking mechanism for the second bore 28 can include thelocking sleeve 16 and two locking balls 74 (as shown in FIG. 3D). Thelocking sleeve 16 can include a channel 86 configured to receive theelongate body portion 60 (as shown in FIGS. 3A-3C) of the plungerportion 14. As illustrated in FIG. 4B, the external surface 89 of thelocking sleeve 16 can define one or more grooves 88. The one or moregrooves 88 can engage with locking arms 108 of the locking lever 22 (asshown in FIG. 8). The engagement between the locking arms 108 and thelocking lever 22 can enable the locking sleeve 16 and the locking bar 18to move between the first position and the second position when thelocking lever 22 is actuated, as discussed herein.

FIG. 4C illustrates a cross-section view of the locking sleeve 16 inFIG. 4A along lines 4C-4C. The locking sleeve 16 can include one or morelocking balls 94 configured to engage with the one or more openings 56(illustrated in FIG. 3A-3C) of the plunger portion 14. In an example,the internal surface 93 of the locking sleeve 16 that defines thechannel 86 can include at least one ramped surface 92. In the exampleillustrated in FIG. 4C, the locking sleeve 16 includes two rampedsurfaces 92 and two locking balls 94. The ramped surfaces 92 can bepositioned, when assembled, near the opening 56 in the plunger portion14.

While the locking lever 22 is in the first position, the locking balls94 can be positioned near a first end 91 of the ramped surface 92 andpartially extend through the opening 56 in the plunger portion 14 andcan fit into a mating recess of an orthopedic device. The engagementbetween the locking balls 94 and the mating recess of the orthopedicdevice can prevent axial movement of the orthopedic device. The rampedsurfaces 92 can interact with the locking balls 94 as the locking lever22 is transitioned from the first position (e.g., locked positioned) tothe second position (e.g., unlocked position). For example, as thelocking lever 22 transitions form the first position to the secondposition, the locking sleeve 16 can move relative to the plunger portion14. As the locking sleeve 16 moves relative to the plunger portion 14,the relationship between the ramped surfaces 92 and the locking balls 94changes such that the locking balls 94 are substantially positionedwithin a cavity 95 formed by the ramped surfaces 92. Thus, while thelocking lever 22 is in the second position, the locking balls 94 are notpositioned within the second bore 28 of the plunger portion 14 and donot engage the orthopedic device positioned within the second bore 28(as shown in FIG. 3C).

FIG. 5 illustrates a front view of the locking bar 18, as constructed inaccordance with at least one example. The locking bar 18 can be part ofa locking mechanism configured to couple an orthopedic device within thefirst bore 10. The locking mechanism can include the locking bar 18 andtwo locking balls 74. The locking bar 18 can include a distal lockingbar 96, a proximal locking bar 97, and two locking arms 98. Each of thetwo locking arms 98 can include a ramped surface 102 that defines acavity 103. The ramped surfaces 102 can be positioned, when assembled,near the openings 40 extending into the interior of the first bore 10such that the ramped surfaces 102 can engage with the locking balls 74.The locking balls 74 can secure the engagement between the first bore 10and an orthopedic device positioned within the first bore 10. Forexample, while the locking lever 22 is in the first position, a portionof each locking ball 74 can extend into the first bore 10 and can engagewith a mating recess of an orthopedic device positioned within the firstbore 10.

FIG. 6 illustrates a partially assembled orthopedic device holder 2 (asshown in FIG. 1), as constructed in accordance with at least oneexample. As illustrated in FIG. 6, at least the distal locking bar 96 ispositioned within and moveable along the longitudinal slot 58 of theplunger portion 14. The resilient member 20 can be positioned around aproximal end 24 of the plunger portion 14. The resilient member 20 canalso be positioned between the distal locking bar 96 and the proximallocking bar 97. The proximal end 19 of the resilient member 20 isconfigured to contact the ledge 38 (as shown in FIG. 8) defined by thebody portion 4.

FIG. 7 illustrates a partially assembled orthopedic device holder 2 (asshown in FIG. 2), as constructed in accordance with at least oneexample. As illustrated in FIG. 7, the locking sleeve 16 and theresilient member 20 are positioned around the plunger portion 14. Theresilient member 20 can be positioned between the distal locking bar 96and the proximal locking 97 (as shown in FIG. 6). A proximal end 110 ofthe locking sleeve 16 can contact the distal locking bar 96 of thelocking bar 18. The locking lever 22 includes locking arms 108 that cancouple to the body portion 4 via locking bar 106. For example, thelocking bar 106 can extend through locking hole 42 (as shown in FIG. 2B)of body portion 4. As illustrated in FIG. 7, the locking arms 108 arepositioned within the groove 88 (as shown in FIG. 4B) defined by thelocking sleeve 16. While locking lever 22 is in the first position(e.g., a locked configuration), the resilient member 20 is in anexpanded state. Additionally, while the locking lever 22 is in the firstposition, a portion of the locking balls 74 extends into the first bore10 and a portion of each of the locking balls 94 extends into the secondbore 28. As the locking lever 22 is transitioned from the first position(locked configuration) to the second position (unlocked configuration)(e.g., by providing force in the direction of direction arrow 104), thelocking arms 108 can move the locking sleeve 16 and the locking bar 18relative to the plunger portion 14 thereby compressing the resilientmember 20.

As the locking sleeve 16 moves relative to the plunger portion 14, theramped surfaces 92 of the locking sleeve 16 interact with the lockingballs 94 such that the locking balls 94 are positioned within the cavity95 formed by the ramped surfaces 92. In other words, the locking balls94 are no longer engaging the openings 56 of the plunger portion 14.Similarly, as the locking bar 18 moves relative to the plunger portion14, the ramped surfaces 102 of the locking bar 18 interact with thelocking balls 74 such that the locking balls 74 are positioned withinthe cavity 103 formed by the ramped surfaces 102. In other words, thelocking balls 74 are no longer engaging the openings 48 of the bodyportion 4.

FIG. 8 illustrates an assembled orthopedic device holder 2, asconstructed in accordance with at least one example. The locking lever22 can be operable coupled to the body portion 4 via the locking arms108 and the locking bar 106. The locking sleeve 16 and the resilientmember 20 can be positioned around plunger portion 14. The resilientmember 20 can be positioned between the distal locking bar 96 and theproximal locking bar 97 (as shown in FIG. 6) where the proximal end 19of the resilient member 20 engages the ledge 38 of the body portion 4.As illustrated in FIG. 8, the orthopedic device holder 2 is in a firstposition, which is a locked configuration. That is, the locking balls 74and 94 are partially positioned within the first bore 10 and the secondbore 28, respectively. As the locking lever 22 transitions from thefirst position to the second position (e.g., applying force in thedirection of direction arrow 104), the locking arms 108 apply a force(e.g., a downward force) to the locking sleeve 16 and the locking bar18. The locking sleeve 16 and the locking bar 18 can move relative tothe plunger portion 14. As the locking sleeve 16 and the locking bar 18move relative to the plunger portion 14, the resilient member 20 becomescompressed as the space between the ledge 38 and the distal locking bar96 decreases.

As the locking lever 22 transitions to the second position, the lockingarms 98 can move within the indentations 50 of the body portion 4. Asthe locking arms 98 move within the indentations 50, the relationshipbetween the ramped surfaces 102 and the locking balls 74 changes suchthat the locking balls 74 are substantially positioned within a cavity103 formed by the ramped surfaces 102, as shown in FIGS. 5 and 6. Thus,while the locking lever 22 is in the second position, the locking balls74 are not positioned within the first bore 10 of the body portion 4.

As the locking lever 22 transitions to the second position, the lockingsleeve 16 moves along the plunger portion 14. As the locking sleeve 16moves along the plunger portion 14, the relationship between the rampedsurfaces 92 and the locking balls 94 changes such that the locking balls94 are substantially poisoned within a cavity 95 formed by the rampedsurfaces 92, as shown in FIG. 4C. Thus, while the locking lever 22 is inthe second position, the locking balls 94 are not positioned within thefirst bore 10.

FIG. 9 illustrates an orthopedic device 120 within the first bore 10 ofthe orthopedic device holder 2, as constructed in accordance with atleast one example. In the example illustrated in FIG. 9, the orthopedicdevice 120 is positioned within the first bore 10 of the body portion 4.The orthopedic device 120 includes a tri-lobe cross-section shape andhas three substantially flat surfaces 122A-C that correspond to thethree substantially flat surfaces 34A-C of the first bore 10. If arotational force 124 is applied to the orthopedic device holder 2, theorthopedic device holder 2 and the orthopedic device 120 can rotatetogether as the edges of the tri-lobe shape of the orthopedic device 120engage the interior surface of the first bore 10. In an example,diameter 123 can be about 7.0 millimeters to about 7.5 millimeters,while diameter 125 can be about 6.3 millimeters to about 6.8millimeters. However, other diameters are possible.

FIGS. 10-12 illustrate portions of various orthopedic devices 120 thatcan be used with the orthopedic device holder 2 (as shown in FIG. 2), asconstructed in accordance with at least one example. Examples oforthopedic devices 120 include, but are not limited to, femoral ortibial intramedullary drills, headless pin drivers, hex screw drivers,reamers, tibial intramedullary rods, femoral intramedullary rods, amongothers. The orthopedic devices 120 can each include an engagementportion 132 that is inserted into the bores of the orthopedic deviceholder 2 (e.g., bore 10 or bore 28 as shown in FIG. 1). As shown inFIGS. 10-12, the engagement portion 132 includes a circumferentialgroove 128 that is configured to receive a portion of one or morelocking balls (e.g., locking balls 94 or locking balls 74). The diameter126 of the engagement portion 132 can be substantially the same or varyfrom the diameter 130 of the remaining portion of the orthopedic device120. As illustrated in FIG. 10, diameter 130 is substantially the sameas diameter 126. As illustrated in FIG. 11, diameter 130 is greater thanthe diameter 126. As illustrated in FIG. 12, diameter 130 is less thanthe diameter 126. However, regardless of the diameter 130, theorthopedic device 120 can be coupled to the orthopedic device holder 2(as shown in FIG. 1).
